2) prerelease auctions. These are domains where the auction venue has contracted with the registrar, like Fabulous or Moniker, to auction off non-renewed domains. Just before a domain enters the pending delete process, it goes to a private auction to any person who has backordered the name. Some people feel that back links on these type of auctions still provide a SEO benifit. My testing indicates that there is zero SEO benifit when these domains are redirected into another site. So if you get a domain with "pink squirels" in a lot of achor text to a domain and then point it at your domain, you don't rank for "pink squirels"
See https://www.domainsherpa.com/domain-name-dictionary/life-cycle-of-a-typical-gtld-domain-name/. They start it in auction listings after it expires and before pending delete. I don’t know the exact dates, but if you monitor it you’ll see it go from auction, to closeout, to drop. You’ll need an auctions.godaddy.com account (I believe $5 per year) to bid and buy.
There is a secondary registrar check built-in, so shouldn't happen very often, so that's the amount external domains we found. Then out of those how many of them are expired domains we've found which will appear in here or in any of the other ones, depending on which type of crawl were running, and that's just simply how long this crewel has been running. So we've got a lot of the similar settings here, in the search query crawl. We have how many queries have been blocked, which you shouldn't get many with any blocked because you're, not hammering google, you know you're sending one query and then processing the results and then sending another query see not scraping Google all all at once. So that's how many queries we've done and how many we've got left to process.

What DomCop does for you, is show you a list of all these domains along with important metrics for every domain. These metrics, along with our powerful filtering and sorting capabilities, will help reduce the size of the daily list from 200,000+ to just a handful of the very best domains. What would take you hours, will now literally take you seconds to do.
If it contains any of those, then I am going to crawl it. Otherwise, I'm not going to because it's probably just something like an Amazon listing. Okay lets move on to the endless cruel. So this is the endless crawl. Basically, here you put your seed websites, one will do if it's a big website, because there's probably loads of domains on it. If it's a tiny, tiny a website, then you might want to stick a few more in so, as I was saying before, it will crawl on all the pages on these websites and then for each external domain that it finds on that website. It will check whether it's expired if it's not expired, it'll try and crawl it and then it will start the loop again, it'll try and take all the domains from there check that they are expired.
For many reasons, these domain names expire and become available to the market. Perhaps the domain renewal fees are unpaid. The owner no longer needs the domain or business came to a halt. With the large pool of domain names that become invalid daily, investors who are looking to cash in on the traffic that they generate have to do extra work to find the most profitable every day. The trick is to find expired domains.
Quite a lot of the time majestic trust flow will be great but ref domains below 10 but when I check ahrefs its considerably higher for ref domains. Without ahrefs I would of passed over these domains and missed out. Worthwhile addition if your building a lot of pbns. I also use linkultra backlink for my final spam check as it checks language,site type and if backlinks are comment, profile spammed etc enabling me to check if the backlinks of the domain are solid very quick.
Domain Hunter Gatherer also makes expired domain detection less painful. As I've mentioned above, finding drop domains on your own can be like taking shots in the dark, or trying to find a needle in a haystack. You’re more than welcome to try it, but I’m telling you, it’s not going to be a pleasant experience. With Domain Hunter Gatherer, you have many different options on how to search for drop domains. You can enter a search term and it will spit out sites that you can then crawl for dead links. You can then filter these dead links to see if they can be registered. You can also enter a site URL of a competitor and get dead links that way. You can even import web pages from Wikipedia or other websites to scan for dead links.

DomCop has a great offer that all of you buying expired domains should consider. For the price of a couple domain names, you can use DomCop for a month, snag some excellent domain names, which would otherwise cost you thousands of dollars. If you're considering expired domain software and don't have the knowledge to program your own crawler, I'd lean towards DomCop.

Although I have one query (this answer does answer it, but I have a doubt)… I just bought a domain which had the creation date as 2010 but after acquisition upon checking I found that it has been reset to 2014. So, from what I understand from your article, this could not be undone anyways because this particular domain’s status said as ‘Expired’ and I got it for under $10 from godaddy?
However, what do you think about buying expired high PR domains and creating local directories, business reivew, and event calendar sites that actually provide a value to the community? Then include a sponsored link from local business that is trying to rank? Do you think a method like that is a. morally soluble and b. viable long-term because it creates value?
Warehousing: I have no clue to a percentage of warehoused domains but I know it happens. Tucows even admitted it on my blog “I know you don’t like that we’re allowed to select expiring names for the Tucows Portfolio rather than letting them all go to auction or drop but that seems to be something we have to agree to disagree about.” ~ Ken Schafer (1st comment) http://www.dotweekly.com/could-you-explain-tucows
The third option is the one that's the most time consuming but also has its benefits. It's like having a successful restaurant and buying another restaurant and operating them simultaneously. They're not the exact same restaurant, but both are popular in their own right and make you money. The same goes for Option #3. You could update the content on the old domain and sell the same products that you're selling on your current site. If you can get both sites to rank alongside each other in the SERPs, you're increasing your conversion chances and sales potential.
The bottom line is, drop domains deliver traffic. How come? When people register a drop domain and build a website on that domain, they often attract backlinks. They also can update their website and generate a community or a brand. Whatever the case is, there are four things that happen that results in traffic for those websites. They create a backlink footprint, which drives direct traffic. This backlink footprint also produces SEO benefits. The more these website owners promote their website, the more goodwill they build up in their target niches and online communities. Finally, the more they manage their online blog, website or information site, they gain some sort of presence on social media.

To get the most from GoDaddy Auctions, you should first decide on the way you want to evaluate the domains. Domainers tend to look at the words in the domain name, while SEOs care about the backlink equity. If you are a domainer, you should look at Estibot, Domain Index or Valuate scores. If you are an SEO, you should look at the Ahrefs, Moz and Majestic metrics to gauge the value of the backlinks. Once you have figured this out, you should look at these numbers for every domain you find on GoDaddy Auctions. Do not be afraid of bidding on the Closeout auctions, as you can get good domains for cheap.
